因聚焦问题导致，只需要再ScrollView得子控件添加一行属性：android:descendantFocusability = "blocksDescendants"

     <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:descendantFocusability="blocksDescendants"
            android:orientation="vertical">

API描述如下：android:descendantFocusability

Defines the relationship between the ViewGroup and its descendants when looking for a View to take focus.

Must be one of the following constant values.

该属性是当一个为view获取焦点时，定义viewGroup和其子控件两者之间的关系。

属性的值有三种：

        beforeDescendants：viewgroup会优先其子类控件而获取到焦点

        afterDescendants：viewgroup只有当其子类控件不需要获取焦点时才获取焦点

        blocksDescendants：viewgroup会覆盖子类控件而直接获得焦点
